There's a stranger in my bed There's a pounding in my head Glitter all over the room Pink flamingos in the pool I smell like a mini-bar DJs passed out in the yard Barbies on the barbecue Is this a hickie or a bruise Pictures of last night ended up online I'm screwed, oh well It's a blacktop blur But I'm pretty sure it ruled. Damn. Last Friday night Yeah we danced on table tops And we took too many shots Think we kissed but I forgot Last Friday night Yeah, we maxed our credit cards And got kicked out of the bar So we hit the boulevard Last Friday night We went streaking in the park Skinny dipping in the dark Then had a menage a trois Last Friday night Yeah I think we broke the law Always say we're gonna stop, oh, whoa-oh This Friday night, do it all again T.G.I.F. T.G.I.F. T.G.I.F. T.G.I.F. T.G.I.F. T.G.I.F. ["E.T."
